FLANGlNG-IVIACHINE.

Specification of Letters Patent.

Patented July 3, 1906.

To all whom, it' may concern:

Be it known that I, Louis N. INICOARTER, a citizen of the United States, residing at Norristown, Pennsylvania, have invented certain Improvements in Flanging Machines, of which the following is a specification.

My invention relates to certain improvements in machines for fianging metal plates to form heads for boilers, drums, vats, and other containers.

The object of my invention isto improve and simplify the construction of Hangingmachines and to-provide means whereby the parts can be driven by electric motors.

In the accompanying drawings, Figure l is a side view of my improved flanging-machine. Fig. 2L is a sectional plan view on the line 2 2, Fig. I. Fig. 2b is a continuation of the plan view Fig. 2a, showing one of the motors and the main driving-shaft. Fig. 3 isa sectional view of the flanging-roller carrier on the line 3 3, Fig. 4. Fig. 4 is a sectional view on the line 4 4, Fig. 3. Fig. 5 is a perspective view of one of the adjusting-blocks illustrated in Fig. 3. Fig. 6 is a sectional view of the mechanism for driving the carriage. Fig. 7 is a sectional view on' the line 7 7, Fig. l and Fig. S is a side view illustrating one of the centering-arms and connece tions.

A A are two beams supported on suitable foundations on each side of a pit, forming the bed-plate upon which the lower part of the mechanism is mounted.

Al is the upper frame, supported on suitable standards A2, secured at their lower ends to the beams A.

B is a vertical shaft mounted in a bearing a, situated between the beams A and having its lower end resting in a step-bearing c on a frame C, hung from the under side of the beams A by legs C. In one of the legs C is a bearing c for the driving-shaft BQ which has a bevel-pinion b at one end which meshes with a bevel-wheel b2, secured to the shaft B.

The driving-shaft B is connected to the armature-shaft of an electric motor B2 by gearing, as illustrated in Fig. 2b, the motor in the present instance being mounted in a pit below the floor.

or beam A', and the plunger can be adjusted l so as to move its head e toward and from the head b of the shaft B and is for the purpose of clamping the plate to be flanged onto the head b.

Mounted on the beams A, forming the bedplate, are two slides F and G. The slide F carries a vertical pin f, on which is mounted the roller j", over which the plate is flanged. This roller can be moved toward and from the head l) by shifting the slide F. On each side of the slide is a lug through which passes a screw F', mounted in bearings on the side of the bed-plate, so that on turning the screws the slide can be adjusted.

On the slide G is a segmental guideway G', in which is a carrierG2, and mounted in bearings on the carrier is a Hanging-roller g, which can be so manipulated as to turn the edge of a plate clamped between the heads over the roller f. The slide G can be moved by means of screws G3 G3, Fig. 2, which have their bearings in the bed-plate A and pass through threaded lugs on the under side of the slide.

The carrier G2 is turned in the segmental guideways G, in the present instance by a shaft g2, having a pinion g3, which lmeshes with a segmental gear g on the carrier G2. The shaft g2 in turn is geared to a driving shaft G4 by bevel-gears g4 g4. This shaft G4 in the present instance is rectangular in crosssection and passes through a rectangular opening in the hub g5 of a sprocket-wheel gf. This hub is mounted in a bearing 97 and flanged, so that it will remain in position in the bearing while the shaft G4 slides withthe carriage G. The shaft in some instances may be round and have a spline cut therein to receive a key on the hub, so that it can slide freely through the hub, but must turn with it. The sprocket-wheel g is geared to a wheel 97 on the armatureshaft of an electric IOC motor Gv by a chain g8'. The motor is mountj cessed to receive the sliding part H, which has bearings h for the spindle of the roller g. The parts H and H each have a double bevel h2 and h2, respectively, and mounted between the two parts are tapered blocks I I 'of the form clearly shown in Fig. 5. These blocks have a rib at each corner, which enter undercut grooves in the parts H H', thus coupling the part H to the part H, but allowing the latter to be adjusted.

Passing through the blocks I I is a right and left handed screw I mounted in sliding bearings i i. The screw is provided with a handle fi, by which it can be turned so as to shift the blocks toward or from each other to regulate the position of the roller g.

rlhe mechanism for moving the screws F and G3 by power is constructed as follows: J is an electric motor mounted on a bracket a', projecting from the side of one of the uprights A2. The shaft of this motor is belted to a shaft J by a chain belt j, which passes around the wheels y" y2. This shaft has two gear-wheels lc 7c. The wheel k meshes with a pinion k2, loose on a shaft K, and the wheel 7c meshes with a pinion m, loose on the eX- tended hub m of a wheel M.

Each of the pinions k2 and fm have clutchteeth at one side, and splined to the shaft K is a clutch k3, and splined to the hub M is a clutch m, so that on throwing either of the clutches into operative position either one or both parts K and M will be driven by the motor.

Keyed to the shaft K is a gear-wheel K, which meshes with pinions c* on the ends of the screw-shafts G3 G3, which control the movement of the carriage G, and the wheel M meshes with pinions m2 m2 on the ends of the screw-shafts F F, which control the movement of the carriage F.

On the clutch m is a hand-wheel m3, and on the end of the shaft K is keyed a handwheel lcs, so that either set of screw-shafts can be turned by hand, if desired. The clutches are shifted in the present instance by levers m4 and k6, arranged to be locked to segments carried by the frameiof the machine.

In order to center the plate in the machine, I provide four centering-slides N, Figs. 2a and 8, which have arms N extending above the floor and in line with the plate to be flanged, so that the vertically-arranged rollers n are in line with the plate, which is mounted on the head b.

Each slide N is mounted on rods 'n' n', supported by bearings n2 n2. The rods are preferably rectangular in cross-section, as shown, and between each pair "of rods is a screw-shaft N2, which passes through a threaded lug n3 on the under side of the slide N. On the inner end of each screw N2 is a bevel-pinion p, which meshes with a bevelwheel P, mounted loosely on the vertical shaft. This wheel is driven by a power-shaft P, Fig. 2a, which has a pinion p', meshing with said wheel, and at the opposite end of the shaft is a gear-wheel p2, which meshes with a pinion on the armature-shaft p3 of the motor P2. When the shaft P is set in motion, all the screws are driven, causing all the slides N to travel toward or from the center of the machine.

The operation of the machine is as follows: If a plate is to be flanged, it is heated to the proper degree, then placed between the heads b and e, the centering device is set in motion, and as the slides N travel toward the center of the machine they adjust the plate until it is central. Then the head e is lowered and the plate is firmly clamped to the head b, after which the arms are withdrawn. The slide F is then adjusted to the proper position, as is also the slide G. Then the motor G5 is set in motion to turn the carrier of the Hangingroller g, which as it travels in the arc of a circle turns down the edge of the plate as the plate is rotated, forming a flange over the anvil-roller f After the flange is formed the slide G is backed off, as is also the head e, after which the anged plate can be removed from the machine.

All the parts are driven by electric motors, there being in the present instance a motor for each special train of mechanism.
